The typical HP hose has a 7/16-inch male at the end that screws into the first stage regulator HP port, and a 7/16-inch female at the end that screws on to the SPG.
Male Fitting to HP port
- 7/16 x 20 UNF male threads
- Brass with electroless nickel plating

Female Fitting to SPG

Swivel-Pin Air-Spools — Please note that all high pressure hoses use a swivel pin air spool with two tiny O-rings to mate the swivel connector on the hose to the fitting on the gauge. The airspool is not included with the hose, but we recommend replacing the air-spool when replacing the hose. The standard 'shoulder' air-spool has the flange in the centre. Some SPGs, typically the plastic body ones, may only accept a 'bullet' air-spool without a shoulder. We stock the standard 'long' bullet air-spool as well as the less commonly used 'short' bullet air-spool.
Mount Martha, Kilburn Grove
Shore Dive | Shore access
Depth: 2 m (6.56 ft) to 6 m (20 ft)
Kilburn Grove, Mount Martha is a dive on a nice reef out from Mount Martha Beach South. Entry and exit are from the beach. Head north-west out from the beach snorkelling on the surface and eventually, you'd start to see reef under you in about 5 metres of water. Descent and go around the reef. Keep plenty of air in your cylinder for the journey back to shore.
This site is also known as Tombstone Reef, after the vertical tombstone like rocks on one side of the reef.
Parking is available in the car park opposite Kilbourn Grove road. There can be plenty of boat traffic so always tow a buoy with a dive flag displayed.
See WillyWeather (Mount Martha) as a guide for the tide times and the height of the tide.
Traditional Owners — This dive site is in the traditional Country of the Boon Wurrung / Bunurong people of the Kulin Nation. This truly ancient Country includes parts of Port Phillip, from the Werribee River in the north-west, down to Wilson's Promontory in the south-east, including the Mornington Peninsula, French Island and Phillip Island, plus Western Port. We wish to acknowledge the Boon Wurrung as Traditional Owners. We pay respect to their Ancestors and their Elders, past, present and emerging. We acknowledge Bunjil the Creator Spirit of this beautiful land, who travels as an eagle, and Waarn, who protects the waterways and travels as a crow, and thank them for continuing to watch over this Country today and beyond.

DISCLAIMER: No claim is made by The Scuba Doctor as to the accuracy of the dive site coordinates listed here. Should anyone decide to use these GPS marks to locate and dive on a site, they do so entirely at their own risk. Always verify against other sources.
The marks come from numerous sources including commercial operators, independent dive clubs, reference works, and active divers. Some are known to be accurate, while others may not be. Some GPS marks may even have come from maps using the AGD66 datum, and thus may need be converted to the WGS84 datum. To distinguish between the possible accuracy of the dive site marks, we've tried to give each mark a source of GPS, Google Earth, or unknown.
